TISAS PX-5.7 FO Raptor | 5.7x28mm | 4.8 in

The TISAS PX-5.7 FO Raptor is a full-size polymer-frame handgun built around the 5.7x28mm cartridge. It ships with a 4.8 inch threaded barrel and a QPQ (Tenifer) slide/barrel finish, and comes equipped with a fiber-optic front sight and an adjustable rear sight for rapid target acquisition. The slide accepts a Glock-compatible footprint for a wide range of aftermarket optics and plates.

For a reliable sighting solution under $1,000 that pairs with the PX-5.7’s Glock-compatible slide, consider a compact red-dot such as the Holosun HS507C for fast, intuitive aiming without adding excessive bulk.

Common uses for this handgun include organized range training and competitive target work where the cartridge’s flat trajectory and low recoil can be leveraged for rapid, accurate follow-up shots.
